I am running NetworkManager version 0.9.4.0 on Ubuntu 12.04 LTS and the bug seems to be still present. Here follows the content of my file /var/run/nm-dns-dnsmasq.conf:
server=8.8.8.8 server=2001:14b8:0:3401::6 server=2001:1418:10:2::2 In my case I have IPv4 DNS server statically configured and IPv6 DNS servers from DHCPv6. I also tried to get both v4 and v6 DNS servers from DHCPs but hothing changed: IPv4 DNS are always preferred. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/936712 Title: NetworkManager should put IPv6 DNS servers before IPv4 DNS servers in dnsmasq configuration (and possibly resolv.conf) Status in “network-manager” package in Ubuntu: Fix Released Bug description: In cases where you are indeed on a dual-stack network and received DNS information from either SLAAC or DHCPv6, these should be used before any equivalent IPv4 data (usually a fallback/compatibility layer in such environment). As an example, here's my generated /run/nm-dns-dnsmasq.conf on an up to date 12.04 system: server=172.17.20.30 server=172.17.25.30 server=172.16.20.32 server=2001:470:c364:1020:e084:d1ff:fe38:c4f5 server=2001:470:c364:1025:8837:98ff:fe43:90e6 server=2001:470:b4e9:1020:218:51ff:fe5a:9949 The result is that dnsmasq will only use the IPv6 dns servers if all 3 IPv4 dns servers are marked as failed. As dnsmasq is perfectly able to detect and avoid broken DNS servers, favoritizing IPv6 servers shouldn't cause any damage even in environment where the information received by NM is wrong.
